Answer:
Amphibians such as lizards, birds, and spiders are three main predators of the swallowtail butterfly [Papilionidae family]. A fourth main predator may be humans. Humans become butterfly predators in three main ways. They're predatory as children before realizing that butterflies aren't playthings or toys. They're predatory as collectors. They're predatory as developers, home gardeners and landscapers before realizing the importance of natural habitat protection.
